Can't access network printers after upgrading to X (XP Pro)

When I was using Win2K on my computer at work I had no problem printing to the other network printers that were installed on the network. A few months ago I upgraded to XP Pro and have noticed that sometimes (often) when I try to print, some of the network printers are "unavailale". I never know when I will be able to print and when I won't. More often than not the when I open the "Printers and Faxes" window the status of the printers is "Opening". When I double click on the printer, after a few long minutes I get the message "Access denied, unable to connect." Everyone else who isn't using XP Pro has no problem printing to any printer any time. What's the problem with XP Pro?

The automatically search box was checked. I unchecked it.
The Guest account was diabled. I enabled it.

Unfortunately, I still don't have access to two out of three printers.

Wait a second. I spoke too soon. I just checked again and all three printers are available. I'm not sure which of the suggestions worked, but now it's working like a charm. Thanks a million!!! <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
